ICP Furnace Control Board Kit for RGS180HFEA0AAAA — OEM Part 1183618 | Ships Today

Overview

This OEM control board kit (part number 1183618) is the integrated furnace control for the ICP / Tempstar / Heil RGS180HFEA0AAAA. The board is the brain of the furnace: it sequences the ignition cycle, monitors the pressure switch and limit safeties, controls the inducer and blower motors, and manages timing and flame proving. When a control board fails you may see no response to a thermostat call, blower motors that won't start or won't stop, repeated lockouts, or fault codes flashed on the diagnostic LED. The kit supplies the correct OEM board so the furnace returns to safe, factory-spec operation.
